Why did they name themselves ''smosh''? whats the significance?

It is a very long story, but here it goes. Rory the smiling squirrel was going for a walk one day. He said hello to Mr. Sun, and to the seven clouds in the sky, whom he had thoughtfully named Horbert, Gilfred, Kilzo, Bofert, Lolput, and Wendell. His best friend Sam the anteater though, disagreed. HE wanted to name the clouds Chuckles, Mr. Fluff-ums, Happy, Lucky, Sparkles, Giggles, and Puffy. So, Sam decided to act. He pulled out his feather, and proceeded to tickle Rory to death, who choked on his own laughter. This made Sam laugh, and pretty soon there were two dead animals, and not a cloud left in the sky. Which suited the vultures just fine.

Its an inside joke for a mosh pit or something like that.

Because smosh is an awesome name
